An internal combustion engine uses fuel, of energy content 44.4 mj/kg, at a rate of 5 kg/h. if the efficiency is 28%, determine the power output and the rate of heat rejection

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

In an experiment, how can i change human errors? be specific.
